recommendations! Published in 2021 at "Environmental Science and Pollution Research"

DOI: 10.1007/s11356-021-15909-9

Abstract: The removal of sulfur- and nitrogen-containing compounds present in petroleum fractions is necessary to meet the stringent environmental regulations and to prevent the environment and humanity from the threats they pose. Conventional hydro-desulfurization and hydro-denitrogenation… read more here.

DOI: 10.1021/acscatal.2c05590

Abstract: N-doped carbons (NCs) have excellent electrocatalytic performance in oxygen reduction reaction, particularly in alkaline conditions, showing great promise of replacing commercial Pt/C catalysts in fuel cells and metal–air batteries. However, NCs are vulnerable when biased… read more here.

DOI: 10.1021/jacs.3c03634

Abstract: A method for C(sp3)-C(sp3) cross-coupling of amines is described. Primary amines are converted to 1,2-dialkyldiazenes by treatment with O-nosylhydroxylamines in the presence of atmospheric oxygen. Denitrogenation of the diazenes with an iridium photocatalyst then forges… read more here.

DOI: 10.3762/bjoc.21.156

Abstract: Photochemical denitrogenation reactions of bicyclic azoalkanes produce strained bicyclic compounds of interest to synthetic organic chemists. We report a computational study on the mechanism of diazabicyclo[2.2.1]heptenes to address long standing mechanistic questions. Indeed, the mechanism… read more here.
